MACHINE FOR OPENING OUT THE CUR LED EDGES OF TEXTILE WEBS SPECIFICATIONforming part of Letters Patent No. 463,550, dated November 17, 1891.

' Application filed May 14, 1890- Serial No. 351,792. (No model.)

.a citizen of the United States, residing at same direction.

Providence, in the State of Rhode Island,

have invented a new and useful Improvementin Machines for Opening Outthe Ourled Edges of Textile TVebs, of which the followin'g'is aspecification.

My invention consists in the improved construction and arrangement ofthe screwthreaded opening-rollers, as hereinafter fully set forth.

Figure 1 represents a detail top view showing the application of myimproved screwthreaded rollers to a cloth-drying machine. Fig. 2represents a central vertical section of the same with an additionalcylinder of the drying-machine. Fig. 3 represents an enlarged sideview,- and Fig. 4: an end View, of a hollow screw adapted for carryingout my improvement.

In the accompanying drawings, A A represent the frame of a cloth-dryingmachine, and B B the stean1-heated cylinders of the same, the saidcylinders being connectedly driven by means of the gears O O. Thescrew-threaded roller G is provided with a driving-pulley H, and theperiphery of the said roller at each end is provided with theoppositely-directed screw-threads c c, the one being adapted for actionat one edge of the web I and the other for actionat the opposite edge,and the roller G is supported against the forwardly-movin g web I bymeans of the standards D D, the opposite roller G having its bearing inthe opposite arms L L, which are pivoted to the roller G and are firmlyconnected to each other by means of the rod E, over which the Web is tobe drawn, and the roller G is rotated from the roller G by means of thegearsff, so that the adjacent surfaces of the said rollers will move inthe The arms L L are provided With a perforated arc g, by means of whichthe roller G and the rod E may be set at any desired angular positionwith relation to the roller G by the insertion of the pin 71 into theperforation 7; of the arc g and into a perforation in the standard D.The cloth from the batch-roll K, which'is supported by the standards J,or from a loose pile, as the case may be, is first passed over the rod Eand over the roller G, thence under the roller G, over the bar F, andunder and around the steam-heated cylinder 13 of the drying-machine. Therollers G and G are preferably formed by means of the right and lefthand threaded screwsleeves J J, which are made movable endwise upon theshaft k, so that provision may be readily made for running webs ofdifferent widths by setting the screw-sleeves inward or outward upon theshaft of the roller or smaller part In, and the said screw-sleeves maybe held in their set position upon the shaft by means of the set-screwm. By first running the web over the stationary rod E the frayed endsoften found at the edge of the web are prevented from being wound uponthe rapidlyrevolving screw-threaded rollers, so as to cause the tearingand damage of the Web. The screwthread of the rollers may be made in anydesired form, that shown in the drawings being considered as bestadapted for general use.

I claim as my invention 1. The combinatiomwith thescrew-threadedrollers, the one acting upon one side and the other upon the oppositeside of the web, of the pivoted frame for supporting one of the rollers,means for driving the said rollers, and means for adjusting the positionof the movable roller in a vertical plane, substantially as described.

2. The combinatiomwith the screw-threaded rollers, the one acting uponone side and the other upon the opposite side of the web, of the pivotedframe for supporting one of the rollers and the rod adapted to preparethe web for engagement with the rollers, and means for adjusting theposition of the movable roller and rod in a vertical plane,substantially as described. a

3. The screw-threaded rollers for operating
